To be honest, this probably won't work for tracking multiple objects.

If you want a more recent version of this, my GPUImage project, which has a ColorObjectTracking example application in there that is a more modern version of this. I am surprised that this won't build, since all you should need to do is update the deployment target and SDK. I know others have used this as an example application successfully recently.

Hi.
:)

It's now April 2014 (most postings are two years old)

I require an iPhone IOS7 capability to identify and track (multiple) object(s) such as the tennis ball example.
I'm excited about the demo software.

However, the quartz app is the only one that works.
I have XCODE 5.1.1 downloaded onto my development Mac.

Do you have a more-recent update of a tennis ball example source-code, or similar GPU-accelerated Sample Source Code ??

Thanks.

hi levi sujanszky,
i am doing the video application like u have asked in this blog.pls help ma. i was stuck with this problem...

Hi, I am not sure if this is

Hi,
I am not sure if this is the right place to ask for help.
I need help with the default image rotation property of GPUImage. In a simple example, I am reading a video from device library and displaying it using GPUImageMovie Class. The framework automatically rotates to fit aspect in a square GPUImageView. I don't want this to happen. If the videos are in portrait mode then it should be played in portrait mode and if the video is in landscape mode then it should play in landscape mode. Can you please guide me here.
Thanks

but now, i want to add new filters like rainbow,fade - in & out and snow fall ,fast motion, slow motion,etc. How can i do that?? please help me!!

Really nice framework. Do you

Really nice framework. Do you know if somebody ported it to work with android and NDK? How hard might it be to port it to android? It would be nice easier to be able to target both platforms simultaneously.

As an update to this, I

As an update to this, I finally solved out a GPU-based means of whole-image color averaging, which is present in my GPUImage framework. See the ColorObjectTracking example, which is the above sample application rebuilt for GPUImage and which now uses this new GPU-accelerated averaging routine. It's much, much faster and can now track objects at a solid 30 FPS on an iPhone 4.

牛逼，great

Hi Brad, Your example

Hi Brad,

Your example application was very useful to me. But I have a problem, I'm pretty new on this and I want to change the white color to red. The white color I'm referring is the one you used on the threshold method to exchange with the color selected. How can I change this to red? Thanks in advance.
